Background

The Iver3 is a compact autonomous underwater vehicle manufactured by L3Harris OceanServer, part of the L3Harris Technologies defence group. It is a single-person-portable system roughly 580 mm in diameter, capable of operating unattended for up to ten hours at depths of 100 to 200 metres and covering more than 20 km of survey lines on a single battery charge. The Iver3 carries a sensor package spanning bathymetry, side-scan sonar, magnetometer, water-quality sensors and cameras.

More than 50 Iver systems are in active use with the US Navy, making the platform a reference point for allied navies building their own autonomous mine-countermeasure and seabed-surveillance programmes. It sits within the wider L3Harris Iver Suite of AUVs, which ranges from the man-portable Iver3 up to larger systems, and L3Harris has been selected by the US Navy and the Defense Innovation Unit to supply AUVs for expeditionary undersea missions.

Common Questions
What is the Iver3 AUV and who makes it?
The Iver3 is a man-portable autonomous underwater vehicle made by L3Harris OceanServer. It operates up to 10 hours at depths of 100-200 metres, carrying sensors for seabed mapping, side-scan sonar, magnetometry, and water quality monitoring.Source: L3Harris official
What was the Iver3 doing at BALTOPS 2026?
At BALTOPS 2026, the US Sixth Fleet deployed Iver3 AUVs off Liepaja, Latvia, operated by the US Navy's Unmanned Undersea Vehicle Group 1. They conducted seabed mapping and subsurface surveillance as part of the first integration of autonomous undersea vehicles at the operational core of the exercise.Source: USNI News / Army Recognition
How many Iver AUVs does the US Navy use?
The US Navy has more than 50 Iver systems in active service. L3Harris was also selected by the US Navy and Defense Innovation Unit to provide AUVs for expeditionary undersea missions.Source: L3Harris Technologies
